sky-watchers are convinced it fell from space...

The bizarre object was found buried 40 metres underground by excavators working in Siberia, Russia
Do these intriguing images show a UFO that fell to Planet Earth from outer space thousands of years ago, embedding itself deep in the ground?
The bizarre flying saucer-shaped object was dug up during excavation work by a coal mining company in Siberia's Kuznetsk Basin, Russia.
Archaeologists were called in to examine the 'craft', which the excavators believe is a man-made object, describing it as a "mystery."
However, sky-watchers are convinced it fell from space.
The unusual object is almost perfectly circular, with a diameter of around 1.2 metres and weighing roughly 440lbs - that's 31 stone.
Excavator Boris Glazkov, 40, who found the object, said: "I have to say it wasn't hard to see as it was really distinctive and large.
"I've never seen anything like this object, which is obviously man-made out, here in the middle of nowhere before. It is a real mystery." The object weighs around 440lbs - 31 stone
His colleague, Arthur Presnyakov, 38, said: "There were actually two similar objects, but the first one broke as it was being pulled out of the ground by the excavator bucket.
"We thought we saw something sure, because it broke into pieces, but then when the second one appeared we stopped work and carefully removed it from the bucket."
The Kuzbassrazrezugol mining company, which owns the object, said it had been pulled out of the ground at a depth of around 40 metres.
Given that it was embedded so deep underground, it could be older than mammoth bones, which have been discovered in the area at a depth of 25 metres.

Scientists declined to comment further while the investigation is ongoing.
But web-users have their own ideas.
OliPokro20 commented: "It doesn't look man-made to me. Why on earth would a human create such a weird object and bury it so deeply?
"I think it must have come from outer space."
